WPF DataGridTextColumn或DataGridTemplateColumn-在行/单元格中输入的文本 [英] WPF DataGridTextColumn or DataGridTemplateColumn - Text Entered In Row/Cell

问题描述

我大约是C#和WPF的1个月新手.在以下方面，我们将不胜感激:

我有一个DataGridTextColumn和DataGridTemplateColumn.
我已经用一些示例数据预填充了表行/列.
当用户在KEY列行中输入一些文本时，我想:

1.确定用户输入的文本-事件drivien.
2.基于(1)，用与特定KEY行/列数据有关的其他数据填充行.

我的DataGridTextColumn中包含以下内容:

Hi,

I am about 1month new to C# and WPF. Would appreciate some help with the following:

I have a DataGridTextColumn and DataGridTemplateColumn.
I have prepopulated the table row/column with some sample data.
When a user enters some text in the KEY column row, I would like to:

1. Determine the text that the user has entered - event drivien.
2. Based on (1), populate the row with additional data pertaining to the specific KEY row/column data.

I have the following in my DataGridTextColumn:

<DataGridTextColumn.EditingElementStyle>
  <Style TargetType="{x:Type TextBox}">
    <eventsetter event="TextInput" handler="TEXT_ENTERED" />
  </Style>

在我的C#代码中，

In my C# code,

private void TEXT_ENTERED(object sender, RoutedEventArgs e)
{
  TextBox t = (TextBox)sender;
  string name = t.Text;
  Debug.WriteLine(name);
}

当Event ="TextInput"时，TEXT_ENTERED函数不起作用.当我将事件设置为"TextChanged"时，则对于在DataGridTextColumn中输入的每个字符都会得到一个事件.

我要捕获输入的整个文本-通过在"ABC"中输入，然后用回车，鼠标单击其他位置.... etc.

任何帮助将不胜感激.

另一个有趣的事情是，以上内容适用于Visual Studio 2010中的"TextInput"，但不适用于2008年.

谢谢，

Manish

The TEXT_ENTERED function does not work when the Event="TextInput". When I set the Event to "TextChanged", then I get an event for each character entered in the DataGridTextColumn.

I want to capture the whole text entered - either by entered in "ABC" followed by a carriage return, a mouse click elsewhere....etc.

Any help would be appreciated.

Another funny thing is that the above works for "TextInput" in Visual Studio 2010, but not in 2008.

Thanks,

Manish

推荐答案

尽管不是最佳解决方案，但实际上找到了解决方案:

我使用KeyDown作为事件，而不是使用TextInput或TextChanged.
在我的TEXT_ENTERED方法中，我使用KeyEventArgs而不是RoutedEventArgs.
最后，我做到了:

Actually found a solution to this, although it is not the best one:

Instead of using TextInput or TextChanged, I used KeyDown as the event.
In my TEXT_ENTERED method, I used KeyEventArgs instead of RoutedEventArgs.
Finally, I did:

if(e.Key == Key.Return)
{
  // Get the Text
}

我希望事情会更加简单....;)

I wish things were a bit more staightforward....;)

Full snippet:

  <Style TargetType="{x:Type TextBox}">
    <eventsetter event="KeyDown" handler="TEXT_ENTERED" />
  </Style>

C#

private void TEXT_ENTERED(object sender, RoutedEventArgs e)
{
  if(e.Key == Key.Return)
  {
    TextBox t = (TextBox)sender;
    string name = t.Text;
    Debug.WriteLine(name);
  }
}
